The insertq instruction is part of SSE4a, which my modern Intel Core 12th Gen CPU does not support

[jqnatividad]

Are you using a prebuilt binary? If so, try the "portable" variants (they end with 'p' - e.g. qsvp, qsvlitep) as they are compiled with no CPU features enabled.

Otherwise, compile from source on your machine with the "target-cpu=native" rustflag enabled so it will only enable CPU features available on your CPU.

[clin1234]

I got the latest version through https://github.com/dathere/qsv/releases/download/8.1.0/qsv-8.1.0-x86_64-unknown-linux-gnu.zip, and that version triggered the SIGILL

[clin1234]

And yes. running qsvp runs just file. I wonder why the original qsv binary contains SSE4a instructions?

[jqnatividad]

Because its compiled with target-cpu=native on GH Action Runners, and they have SSE4a CPU feature available.

Then surely the pre-built binary zip file should not have the nomenclature x86_64 since it is no longer x86_64 and it is purely amd64 (and not even amd64 in a general sense!)

Downloading qsv-9.1.0-x86_64-unknown-linux-musl.zip does not work on a frame.work intel 13th gen. If you're gonna call it x86_64 then be compatible with SSE4.1 / 4.2 etc.

I feel that you've broken the principle of least surprise with this since there's no obvious 💥BREAKING CHANGE use qsvp if you're on an intel chip in the 5 / 6/ 7/ 8/ 9/ release notes.
